Commentary on Psalms Volume 2 John Calvin
COMMENTARY ON PSALMS - VOLUME 2 is a figurative expression, employed in Scripture to denote the condition or lot with which every man is contented. Accordingly, the reason why God is represented as a portion is, because he alone is abundantly sufficient for us, and because in him the perfection of our happiness consists. Whence it follows, that we are chargeable with ingratitude, if we turn away our minds from him and fix them on any other object, as has been stated in Psalm 16:4, where David explains more clearly the import of the metaphor. Some foolishly assert that God is called our portion, because our soul is taken from him. I know not how such a silly conceit has found its way into their brains; for it is as far from David's meaning as heaven is from the earth, and it involves in it the wild notion of the Manicheans, with which Servetus was bewitched. But it generally happens that men who are not exercised in the Scriptures, nor imbued with sound theology, although well acquainted with the Hebrew language, yet err and fall into mistakes even in first principles. Under the word heart the Psalmist comprehends the whole soul. He does not, however, mean, when he speaks of the heart failing, that the essence or substance of the soul fails, but that all the powers which God in his goodness has bestowed upon it, and the use of which it retains only so long as he pleases, fall into decay.
27. For, lo! they who depart from thee shall perish. Here he proves, by an argument taken from things contrary, that nothing was better for him than simply to repose himself upon God alone; for no sooner does any one depart from God than he inevitably falls into the most dreadful destruction. All depart from him who divide and scatter their hope among a variety of objects. The phrase to go a whoring 691 is of similar import; for it is the worst kind of adultery to divide our heart that it may not continue fixed exclusively upon God. This will be more easily understood by defining the spiritual chastity of our minds, which consists in faith, in calling upon God, in integrity of heart, and in obedience to the Word. Whoever then submits not himself to the Word of God, that feeling him to be the sole author of all good things, he may depend upon him, surrender himself to be governed by him, betake himself to him at all times, and devote to him all his affections, such a person is like an adulterous woman who leaves her own husband, and prostitutes herself to strangers. David's language then is equivalent to his pronouncing all apostates who revolt from God to be adulterers.
28. As for me, it is good for me to draw near to God. Literally the reading is, And I, etc. David speaking expressly of himself, affirms that although he should see all mankind in a state of estrangement from God, and wandering after the ever-changing errors and superstitions of the world,
"Go a whoring, etc.; i.e., forsake God for false gods, which is spiritual adultery." — Sutcliffe. When God is said to have destroyed such as do this, some think there is an allusion to that part of the Mosaic law which doomed idolaters to be punished with death, as guilty of high treason against Jehovah the King of Israel.
